Abstract
The utility model relates to an outdoor current transformer, which comprises a pouring casing and a transformer body arranged in an inner space of the pouring casing. The transformer body comprises a primary winding and a secondary winding. Two current conducting plates extending upwards are fixedly connected with the upper end of the primary winding. Portions of the two current conducting plates protruding outside the pouring casing are provided with folding portions bending outwards respectively. The folding portions are distributed symmetrically with a longitudinal central line of the pouring casing as the center, and an angle formed by the two folding portions is 90 degrees. During wire connecting, space distance between the two current conducting plates is expanded, thereby being convenient for installing workers to install. In addition, the pouring casing comprises an epoxy resin layer and an uvioresistant layer wrapped on the outer periphery of the epoxy resin layer, thereby effectively reducing effects of solar ultraviolet on the transformer and being more reliable and stable.
Description
Technical field
The utility model is specifically related to a kind of Outdoor Current Transformer.
Background technology
As everyone knows, Outdoor Current Transformer comprises winding, a secondary winding and is arranged on the terminals on the said winding, instrument transformer commonly used in the market; The vertical parallel installation of two conductive plates on winding; Space length between the conductive plate of protrusion cast shell is big inadequately, when the staff carries out the wiring installation, and the hand of often stumbling; Extremely inconvenient, and and then reduced operating efficiency.In addition; Existing instrument transformer cast shell all is by the moulding of epoxy resin disposal pouring, has reached enough insulation property, but can't eliminate out of doors under the environment; Solar ultraviolet is to the negative effect of instrument transformer, thereby makes instrument transformer exist potential factor leading to social instability.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, and a kind of easy for installation, reliable and stable Outdoor Current Transformer is provided.
For realizing above-mentioned purpose; The utility model adopts a kind of Outdoor Current Transformer; Comprise cast shell and the device body that places this cast shell inner space; Said device body comprises winding and secondary winding, and one time the winding upper end is fixedly connected with two upwardly extending conductive plates, and the part of protrusion cast shell has the turnover portion of outside bending respectively on wherein said two conductive plates; And said turnover portion is that the center is symmetrically distributed with the longitudinal centre line of cast shell, and the angle between wherein said two turnover portions is 90 °.
Through above-mentioned improvement to prior art, because wiring one end of the conductive plate on winding has been bent certain angle laterally, and with respect to the longitudinal centre line symmetry; Make that the space length between the turnover portion of described two conductive plates is enough big; When carrying out installment works such as wiring the staff, the hand that is unlikely to stumble, the operating space is big; Great convenience is provided, and and then the corresponding installation effectiveness that improved.
As the further setting of the utility model, said cast shell comprises the epoxy resin layer and the uvioresistant layer that is coated on this epoxy resin layer outer circumferential side of one-time cast-forming.The cast shell of this kind structural design effectively reduces the influence of solar ultraviolet to this instrument transformer, reliable and stable more.

Fig. 2 is the front view of device body among this Fig. 1.
Fig. 3 is the left view of Fig. 2.
Embodiment
Shown in Fig. 1-3; The specific embodiment of the utility model is a kind of Outdoor Current Transformer; Comprise cast shell and the device body that places this cast shell inner space; Said device body comprises that a winding 1 is fixedly connected with two upwardly extending conductive plates 3 with 2, winding 1 upper ends of secondary winding, and the part of protrusion cast shell has the turnover portion 30 of outside bending respectively on wherein said two conductive plates 3; And said turnover portion 30 be the center symmetrical distribution with the longitudinal centre lines 4 of cast shell, and the angle between wherein said two turnover portions 30 is 90 °; Make that the space length between the turnover portion 30 of described two conductive plates 3 is enough big, when carrying out installment works such as wiring the staff, the hand that is unlikely to stumble, the operating space is big, and great convenience is provided, and and then the corresponding installation effectiveness that improved; Also obviously can know by Fig. 1; Said cast shell comprises the epoxy resin layer 5 and the uvioresistant layer 6 that is coated on these epoxy resin layer 5 outer circumferential sides of one-time cast-forming; Obviously; The material of the uvioresistant layer here can be chosen through the PP of special processing material etc., also can adopt the mode of the special color ultraviolet ray filtering of coating to realize anti-ultraviolet function.
Claims (2)
1. Outdoor Current Transformer; Comprise cast shell and the device body that places this cast shell inner space; Said device body comprises winding and secondary winding, and one time the winding upper end is fixedly connected with two upwardly extending conductive plates, it is characterized in that: the part of protrusion cast shell has the turnover portion of outside bending respectively on said two conductive plates; And said turnover portion is that the center is symmetrically distributed with the longitudinal centre line of cast shell, and the angle between wherein said two turnover portions is 90 °.
